Eestis on kasutusel mitmeid erinevaid lehmade pidamissüsteeme. Aastate jooksul on
suurenenud vabapidamislautade arv ja vähenenud lõaspidamislautade osakaal. Kõikidel
lahendustel on oma plussid ja miinused. Vabapidamislautades on võimalik valida mitmete
erinevaid lahendusi, nende seas lüpsisüsteemid, asemed, käiguteed ja sõnnikueemaldamine.
Lehmade karjast väljaminek on piimatootmises vältimatu tegevus, see
võib-olla tingitud majanduslikest ja bioloogilistest põhjustest. Sigivus ja karja
taastootmine mõjutab tugevalt ettevõtte kasumlikust. Praakimis otsused tehakse tihti
intuitsiooni ajel, mitte ökonoomiliste näitajate abil. Antud töös selgitatakse seitsme
erineva farmi näitel kuidas pidamistingimused mõjutavad praakimispõhjuste avaldumist.
Väga sarnaste pidamistingimustega farmides domineerisid erinevad praakimispõhjused,
mis on tingitud farmide erinevast majandamisest ja mõjutatud ka subjektiivsetest
tingimustest.
There are many different housing systems represent in Estonia. Over the years there has been an increase of freestall housing and a decrease in the number tie stall farms. Every housing system has its perks and disadvantages. In freestall housing there are many different solutions available among them milking systems, stalls, floors and manure removal. Culling in milk production is unavoidable it can be done for economic and biological reasons. Fertility and reproduction has a strong influence towards farm profitability. Culling decisions are usually made on intuition not on the economical factors. Current study describes the affect of housing system traits on culling on the data of seven farms. Farms with very similar housing conditions showed very different reasons for culling, due to farm specifics and for subjective reasons.
